Abstract

Devices and methods are provided for temporarily and permanently apposing together leaflets of a cardiac valve.

Claims

8-1. The method of claim 1, wherein the method is performed by means of an endovascular approach.

9-2. The method of claim 1, wherein the method is performed by means of a surgical approach.

17. A device for repairing a cardiac valve having leaflets and subvalvular chordae, the device comprising:

a main body configured for delivery to the cardiac valve;

a chordae capturing member associated with a distal end of the main body; and

a fastener application member associated with the distal end of the main body, wherein the fastener application member is used to apply a fastener to the valve anatomy to permanently appose the leaflets at a selected apposition site.

18. The device of claim 17, wherein the capturing member is selectively retractable within and extendable from the distal end of the main body.

19. The device of claim 17, wherein the fastener application member is selectively retractable within and extendable from the distal end of the main body.

20. The device of claim 17, wherein the capturing member comprises two rotatable arms.

21. The device of claim 20, wherein the two rotatable arms are simultaneously rotatable.

22. The device of claim 17, wherein the capturing member comprises a coiled loop.

23. The device of claim 17, wherein the capturing member has a low-profile configuration when retracted within the main body and has an expanded configuration when extended from the main body.

24. The device of claim 17, wherein the main body comprises a catheter.

25. The device of claim 17, wherein the main body comprises a cannula.

26. The device of claim 17, wherein the device is configured to deliver a fastener from outside a patient'"'"'s body to proximate the valve leaflets.

27. The device of claim 26, wherein the device is configured to successively deliver a plurality of fastener.

28. The device of claim 27, wherein the device is configured to hold a cartridge of fasteners.

29. The device of claim 17, wherein the fastener application member comprises a lumen through which a fastener is delivered.

30. The device of claim 17, wherein the fastener application member is configured to restrain a fastener in an undeployed state.

31. A device for repairing a cardiac valve having leaflets and subvalvular chordae, the device comprising:

a main body configured for delivery to the cardiac valve; and

a mechanism at a distal end of the main body configured for capturing chordae and applying a fastener to the valve anatomy to permanently appose the leaflets at a selected apposition site.

32. The device of claim 31 wherein said mechanism comprises a releasable fastener.

33. The device of claim 32 wherein the mechanism further comprises means for selectively opening and closing the fastener.

34. The device of claim 33 wherein the fastener comprises two opposing jaws and wherein the means for opening and closing fastener comprises means for opening and closing the jaws.

35. The device of claim 34 wherein the fastener comprises means for locking the jaws together in a closed position.

36. The device of claim 35 wherein the mechanism is configured to controllably release the fastener from the device.

37. The device of claim 32 wherein the fastener is configured to capture the chordae.
